To 'all ywhom it may concern:

V Be it known that I, JOHN lVILLIsoN, of Derby, Derby county, England, have invented a new and useful Draft-Rigging, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming partof this specification, in which- Figure 1 is a central longitudinal section showing a draft-rigging constructed in accoi-dance with my invention; Fig. 2 is a horizontal section on the line Il--II of Fig. 1; Fig. 3 is a vertical section oil the line III-III of Fig. l; Fig. 4- is a vertical section on the line IV-IV of Fig. 1; Fig. 5 is a top plan view of the spring follower; Fig. 6 is a front elevation thereof; and'Fig. 7 is a perspective view of the buHer plate.

M invention is designed to afford a draftrigglng of simple construction which will automatically adjust itself in central position and will afford advantages of compactness and reat durability.

In the rawings, 2, 2 represent the draftirons or draft-timbers which preferably form part of the car-frame, and between which the draftfrigging is arranged.

3 is the shankv of Vthe coupler, which is preferably set adjustably Within a longitudinal holder-case 4 in which it is movable telescopically so as to vary the extent of its forward projection. In order to adjust 1t l provide the shank with vertical holes 5, 5', 5a, preferably three in number, and I form registering holes 6 at the top and bottom of the case 4, so that when a pin or block ,Tris `inserted through the holes 6 and throught one of the hole'sof the shank it will tie the case 4 and the draw-bar shank together, the latter projecting to an extent which depends upon the location of the particular hole in the shank which is utilized. Forthe purpose of holding and removing the pin 7 I preferably employV a lever S which is fulcrumed in a bracket 9 and is held in locked position by c second bracket 10, from which however it can be detached by raising thel lever and movingit sidewise. The lever eir-V tends through a loop 7 at the lower end of the pin 7, and when the par-ts are in the position shown in Fig. 3 with lthe lever resting on the bracket 10, the'pin is held securely in, the holein the case 4 and draw-bar shank 3. The upper end of the pin is preferably provided with a guiding projection 7 a which fits action.

groove To remove the pin and to permit the draw-bar shank to be adjusted lengt-hwise in the case 4, the operator lifts the lever sllghtly and shifts it sidewise so Pas to vfree it from the bracket-pin, and then pulls it down until its rear end engagesa stopn so asltq draw the body of the pin below the draw,- bur shank, and then 'moves the draw-bar shank lengthwise within the case until another hole 5 is brought into register with the pin. The pin is then raised by lifting the lever 8 so as again to pass it through lthe holes in the case and draw-bar 'shan and the lever iS again seated `on the bracket 10.1

The rear end of the case 4 is connected by a pin 11 with the forward end ofa tail=bolt 12, which extends rearwardly therefrom through a hole in a buffer-plate or stop 1 3.` This buer--plate is setin a vertical 'guideway or recess 14 one bracket 1,5 whioli'is fixed tothe draft-timbers or draft-irons, and on the rear side ofthe buffer-plate is afbllower-plate 16 f having forward `projections 16 which extend through holes 13 in4 the buffer-plate and bear against the rear end of the case 4.

Back of the follower-plate 16 and'encircling the tail-bolt 12 is a spring 17, thel tension of which is adjustable on the tail-bolt by a suitable device, such asa cap 18 and nut 19. The cap 18 is confined by lugs 20 onthe draft-irons so as to have only a. limited' "ilateral movement with the tail-bolt. These lu 20 act as chafing plates to retain the cap 18;.;.in' a central position by their centering The hele in.V the case 4 through which the pin lll passes is slotted as at 21 to permit the draft-rigging to have a longitudinal bufiing movement. The buffer-plate is supported by a suitable device, such as bolts 22 on the bracket 15, and the bracket is preferably provided with lugs 23 which extend in the vertical groove at the edges of the buffer-plate.

When the bufiing force is applied to the coupler-head, the draw bar, 'which is made upl of the coupler-shank 3,' and the case 4, will move rearwardly, such motion lifeing per-" mitted by the slotted connection 21,- and it; will press back the follower-plate 16 by means of the projections-16,. vthus compressing the spring 17 against the cap 18 on the tail-bolt, the latter being held by opposite shoulders 12 Which bear against the front face of the bufer-plate. When a pulling stress is applied to the couplt-r-head it vv'ill draw with it the tail-bolt 12 through the even When there are no stresses of bui'ling or draft, and therefore. vexerts a rearward pulling action on the draw-bar case 4 through the tail-bolt 1.2, this tension will hold the draw-bar :in central position, and when it is deflected will autoniatically restore it to such ent-ral position.

"Silit-hin the scope of my' invention as de fined in the eiaiins the parte may be modified in many 'tva-ys, sinne 1.. The combination of a draivliar shank, a case slidabiy receiving the shank, one of these members having a series of openings and the other member having an opening for successive registration with the series of openings, a pin adapted vto pass through registering openings in the case and,shank, and means associated with the ease for yieldably taking up draft and bufling strains.
